ACPL-C790

ACPL-C79B, ACPL-C79A, ACPL-C790 Precision Miniature Isolation Amplifiers Data Sheet Description The ACPL-C79B/C79A/C790 isolation amplifiers are designed for current and voltage sensing in electronic power converters in applications including motor drives and renewable energy systems. In a typical motor drive implementation, current flows through an external resistor and the resulting analog voltage drop is sensed by the isolation amplifier. A differential output voltage that is proportional to the current is created on the other side of the optical isolation barrier. For general applications, the ACPL-C79A (±1% gain tolerance) and the ACPL-C790 (±3% gain tolerance) are recommended. For high precision applications, the ACPL-C79B (±0.5% gain tolerance) can be used. The product operates from a single 5 V supply and provides excellent linearity and dynamic performance of 62 dB SNR. With 200 kHz bandwidth, 1.6 µs fast response time, the product captures transients in short circuit and...
